    Object distribution has been regarded as one of the most important paradigms for distributed processing since the early eighties. The increasing popularity of digital audio and video applications presents new challenges to the traditional object distribution models. This paper outlines some of important progress of the ANSA Phase 3 project to extend ANSA object model for real-time and multimedia p... View full abstract»

    Research at Lancaster University is aimed at providing system software support for distributed real-time and multimedia applications in an environment of conventional workstations and high-speed networks. Our approach is to use a micro-kernel operating system, specifically Chorus, to underpin both UNIX and real-time applications. A standard UNIX SVR4 `personality' included with Chorus is used to s...

    From a technical viewpoint the support of digital audio and video in computer systems poses many interesting challenges, including thinking in terms of streams rather than units of data, the consequent invention and remodelling of existing support models, the exploitation of emerging hardware, and an acknowledgement of the necessity for trade-offs in delivered quality (or, the Quality of Service Q...

  • Representing appearance in a multimedia information system

    Publication Year: 1994, Page(s):7/1 - 7/4

    It is now generally accepted that future information systems will allow storage and retrieval of speech, images and even full motion video and this has motivated a great deal of work in the area of distributed multimedia systems. However there are other classes of `objects' which can be stored and manipulated using computers. The authors consider how appearance models are one important example of ... View full abstract»

  • An ATM based architecture for supporting multiple video streams-the CHARISMA ATM card

    Publication Year: 1994, Page(s):2/1 - 2/4
    Cited by:  Patents (1)

    The CHARISMA project is a RACE II funded investigation into the operation of networked case handling and work flow support tools. It will utilise mixed-media distributed communications to aid multisite case handling operations, and as such, places considerable demands upon its supporting network architecture. The project will utilise high performance PCs as its workstations and servers. A server m... View full abstract»

  • Scalable multimedia hardware for distributed conferencing systems

    Publication Year: 1994, Page(s):4/1 - 4/3
    IEEE is not the copyright holder of this material | Click to expandAbstract | PDF file iconPDF (160 KB)

    This paper describes our work at the University of Sussex in the field of multimedia conferencing. Our research is directed towards a novel scalable architecture using a modular hardware and software approach. The Sussex multimedia architecture supports distributed multimedia servers and multiple video channels in a windows environment. A key element of the Sussex multimedia architecture is the ME...

    It is now technically possible to construct distributed systems which support audio and video information. These media are inherently time dependent and so their use in combination requires suitable techniques for synchronizing a variety of presentation streams to be available. The steps involved in the capture or retrieval and in the encoding and transmission of these media may take significant p... View full abstract»

  • Why lossy internetworking and lossless ABR ATM services do not go together-RN/94/21

    Publication Year: 1994, Page(s):3/1 - 3/6
    IEEE is not the copyright holder of this material | Click to expandAbstract | PDF file iconPDF (276 KB)

    This paper is about the conflicts between two multiservice network architectures and to some extent, the data transfer perspective for congestion control, in the context of an Internet with some (or most) paths provided by underlying ATM. In the limit, we believe that networks will have excess capacity, and that this will be the model for all traffic control-hence traffic control is about finding ... View full abstract»
